A top or cover piece 22 of wood is I00secured in position on top of the sections by screws 23 and thumb-nuts2i, thus greatly strengthening the block, and holes 25 for screws 26 areprovided at intervals for securing the block to the wall. Screw-holesand clearance-holes are made wherever necessary in the sections in thecustomary manner. Changes and modifications may be made by the skilledmechanic in the construction, proportions, and arrangement of sectionswithout departing from my invention, since I do not desire to be limitedto the form of block as illustrated in the drawings, as it is obviousthat such changes will suggest themselves to suit different requirementsof use.

Having described my invention and in what manner it operates, what Iclaim, and desire to secure by Letters Patent, is-

1. A circuit-block for use in makin branch electrical connections,consisting of two or more sections of insulating material securedtogether by one or more metallic connections attached to each section,such metallic connections having electrical connection with main feedand branch wires respectively, substantially as set forth.

A eircuit-bloek for use in making branch electrical connections,consisting of two or more sections of insulating material, securedtogether by one or more strips of metal, attached to each section, suchstrips having electrical connection with main feed-wires and with branchconnections secured to the sections, respectively, substantially as setforthv The combination, in a multiple circuitblock of two or moresections of insulating material, secured together by strips located oneach side of a central rib formed by the sections, and feed-Wireconnections and branchwire connections respectively, secured to thesections, substantially as set forth.

at. In a circuit-block for use in making branch electrical connections,consisting of two or more sections of insulating material securedtogether by one or more strips of metal attached to each section, havingelec trical connection with main feed-wires, openings in the sides ofthe sections for branch wires electrically connecting with the strips,substantially as set forth.

5. In a circuit-block for use in making branch electrical connectionsconsisting of two or more sections of insulating material, securedtogether by one or more strips of metal attached to each section, havingelectrical connection with main feed-wires; openings through thesections from front to back for branch wires, electrically connectingwith the strips, substantially as set forth.

In testimony whereof I have hereunto set my hand this 25th day ofSeptember, 1895.
